Term and Definition: Replacement Model
The term replacement model is particularly used in the field of industrial property protection, specifically in design law. Replacement models (or designs) refer to designs that ‘fall away’ upon expiration or cancellation of an existing protection right, and which can potentially be newly registered or used. In certain situations, especially in registered design law (now known as design law), the term is associated with the so-called replacement regulation. This concerns the consequences of withdrawal, cancellation, or invalidity of a registered design or utility model and the resulting possibility to activate or assert a “replacement model.”
Legal Basis of the Replacement Model
Registered Design Law and Design Law
The replacement model has its origin in design protection law, which has since been further developed by the Design Act (DesignG) According to § 30 (3) DesignG and the corresponding European regulations, withdrawal or cancellation of a primary design can lead to activation of a previously deferred or dependent design as a replacement model. This provision aims to preserve a certain scope of protection for right holders and secure the right to priority or use in case the original design ‘falls away’.
Utility Model Law
Also in the Utility Model Law the law provides for similar situations. Here, in the context of so-called “branching off”, it is possible to derive a utility model from a patent application. If the patent is not granted or is later revoked, the registered utility model can be activated as a replacement model.
Purpose and Function of the Replacement Model
The replacement model serves to mitigate negative consequences from the expiry, revocation, or invalidation of an industrial property right. By enabling the activation of a deferred or dependent design, the legal position of the original applicant is preserved and the protection gap that would arise from the termination of the main right is closed.
Purpose and Protection Mechanism
- Ensuring legal continuity: In the event of the loss of the original protection right, the replacement model protects against the complete loss of the protection scope.
- Maintenance of Priority: The replacement model can assume the priority of the original application and thus secure its rank in the comparison of protection rights.
- Defense against Imitation: The legal transition to a replacement model ensures that the protection object remains safeguarded against unauthorized imitation and use by third parties.
Requirements and Procedures for Activating a Replacement Model
Requirements
To assert the right to a replacement model, certain legal prerequisites must be met:
- The design must have been formally filed and registered, but with a suspensive effect or deferment in place.
- The original design must cease prematurely, such as through withdrawal, abandonment, expiration, or cancellation.
- The replacement model must be activated or asserted within a certain period and in conformity with formal requirements.
Process in Administrative and Judicial Proceedings
If the main design is cancelled, withdrawn, or declared invalid, the German Patent and Trademark Office (DPMA) or the relevant European authority examines the entitlement to a replacement model. If all conditions are met, the “reinstatement” or entry of the replacement model into the register is executed. Rights and protective effects come into force retroactively from the original filing date.
Legal Importance and Potential Disputes
Legal Relevance
The replacement model has considerable practical significance in industrial property protection, as it provides a follow-up solution for registered rights even after their expiration, thereby protecting innovation and investments in design, technology, and product development.
Disputes and Judicial Practice
Typical disputes relating to replacement models concern:
- Priority Conflicts: Who is entitled to protection at the relevant point in time.
- Formalities related to activation: Whether all requirements for asserting the claim were met.
- Scope of Protection: To what extent the replacement model can claim the same protection scope as the original design.
In proceedings before the DPMA, the European Union Intellectual Property Office (EUIPO), or national courts, a key consideration is whether the transfer of the protection right was smooth and in compliance with all deadlines and formal requirements.
International Aspects and Union Law Regulation
European Union
Union-wide, the protection of designs is governed by Regulation (EC) No. 6/2002 on Community designs. Here too, the legal system allows, in certain cases, the registration and activation of replacement models at the EU level, taking into account national legal specifics.
International Perspective
In the international context, especially when registering designs under the Hague Agreement, replacement models play a role in countries with comparable legal institutions. It should be noted that national differences can exist in terms of scope of protection and activation modalities.
Conclusion
The replacement model is an important instrument for the protection of industrial rights. It enables the continuation of legal protection despite unforeseen lapses of the original right, securing priority and innovation protection. Statutory regulations give applicants the opportunity to respond flexibly to the lapse of a design or utility model and thus ensure continuous legal protection. In industrial property protection, the replacement model thus assumes a central function in safeguarding economic interests.

Frequently Asked Questions
Who bears the burden of proof for the existence of a replacement model?
In legal terms, the burden of proof for the existence of a replacement model generally lies with the applicant of the utility model. This means that anyone claiming the registration of a replacement model must prove that the subject matter of the application is indeed a replacement model and therefore falls under the exception clause of § 2 paragraph 3 no. 1 GebrMG (Utility Model Act). This especially includes demonstrating that the filed technical teaching was not anticipated by an earlier right, due to a lack of actual disclosure of the technical teaching in the state of the art (so-called “missing” disclosure). The applicant must substantiate why particular features were not disclosed, but only implicitly present, during the alleged prior use or in the publication. If this burden of proof is not met, the assertion as a replacement model in examination proceedings or in a dispute will not succeed.
What are the legal differences between replacement models and standard utility models?
Legally, replacement models primarily differ from standard utility models in their distinction from the state of the art and the question of novelty. Under § 2 GebrMG, the replacement model is an exception when a technical teaching was theoretically part of the prior art but could not practically be implemented or was objectively impossible. While, for ordinary utility models, novelty may be destroyed by prior art documents even if not feasible, the law prescribes a special evaluation for replacement models. Practice shows that courts and legal theory especially scrutinize the feasibility of competing suggestions. While a theoretical description is sufficient for standard models, for replacement models, proof must be provided that specific technical instructions were missing or could not be performed.
How do courts examine the actual feasibility in the case of a replacement model?
Courts and patent offices examine the actual feasibility of a replacement model far more strictly than for standard applications. The crucial point is whether a person skilled in the art, based on the overall disclosure and their expertise, can implement the teaching. This assessment considers whether the prior disclosure lacks information, contains contradictions, or whether implementation was technically impossible at the priority date. Furthermore, it is examined whether overcoming these hurdles would have required unreasonable experimentation, independent creative thought, or above-average skills. Judicial examination often relies on relevant, expert opinions and the so-called “average skilled person” standard. If this results in objective infeasibility, the replacement model will be deemed justified.
What happens if it is subsequently determined that the alleged replacement model subject matter was actually feasible?
If it turns out after registration of the utility model that the claimed subject matter was in fact feasible and thus part of the prior art, this can have serious legal consequences. In cancellation proceedings under § 15 GebrMG, the utility model can be revoked for lack of novelty and unmet protection requirements. In addition, claims for damages may arise against the applicant if rights holders or third parties are economically harmed by the improper registration. In certain cases, contestation on the grounds of fraudulent deception (§ 123 BGB) may be considered if the applicant knowingly made false statements. Therefore, utmost care is required when asserting a replacement model.
What is the significance of the replacement model in enforcing protection rights?
The replacement model is particularly significant in legal disputes, as it can be used to overcome alleged obstacles to novelty and enables defense against nullity attacks. In infringement proceedings, it is crucial whether the protection right is substantively valid. Attackers may attempt to undermine the replacement model by demonstrating the feasibility of the earlier prior art. If successful, the status as a replacement model lapses and the protection right is rendered vulnerable. In response, the defense may use technical and scientific arguments to show that the earlier state of the art was merely an ‘unfinished’ construct not suitable for replication by the public.
What role do expert opinions play in disputes over replacement models?
Expert opinions play a central role in disputes concerning replacement models. Due to the often complex technical issues regarding whether a disclosure in the prior art was actually feasible, courts typically engage independent experts. These examine from the relevant professional perspective whether, based on general knowledge and the disclosure at the priority date, practical implementation would have been possible. The statements of experts are decisive for the legal evaluation, as they often provide the only objective basis for deciding on the protectability and validity of the replacement model.
Are there specific deadlines to be observed when applying for a replacement model?
When applying for a replacement model, the general deadlines from utility model law apply, for example for claiming priority or for filing examination and cancellation requests. Additionally, there is an increased duty for the applicant to disclose facts about the qualification as a replacement model early and comprehensively, to enable the office or court to make a proper decision. If the applicant wishes to submit later evidence or indications establishing the existence of a replacement model, preclusion periods and rules for late submissions in procedural orders may apply. Therefore, it is advisable to submit all relevant information at the time of application.
